I am using mc9s12xdp512 controller for our project development.

As part of our development, we are now planning to have Diagnostics for our system.

So as part of this we want to capture and log Watchdog Reset.


For this I tried to write my own ISR or function and tried to assign this to vector table at 0xFFFA. But compiler gave error saying this Vector location is already assigned with System Reset point.


So can someone let me know, is there any way to capture and log failure that Watchdog reset has happened.

Or can you let me know how we can customize the ISR of watchdog?
